Some USB powered programmers do not always reliably program the 21V types. Older obsolete type EPROMs (27128 types) use either a 21V or a 12.5V programming voltage depending on when and by who they were produced.

Universal-Ģ7C256 use a 12.5V programming voltage and program okay using USB powered programmers.

So if you think that using modchips with retro hardware is not morally OK, think that no company would replace Your damaged CD with shooter game without making you pay for each shot in a new, "better" version.1024MAK wrote:Earlier this year I got this "Universal miniPRO EPROM EEPROM FLASH Programmer TL866CS High speed AVR" but have not really put it through it's paces yet (as it means I need to power up a Windows PC). This is a typical marketing extension for "monetizing" not only content and items, but every aspect of a game.

Many old console games come back, but none of them in original form, which usually was some kind of media (doesn't matter MO disc, CD, cartridge or downloadable file) containing a full game. My chip has programmed well and is working.Īfter installation I was thinking about all this retro market. I found that if Vpp is unstable contents may just disappear in few seconds after programming! Now remove the chip, wait a minute, insert and verify again. Answer NO to preserve factory-set calibration and it will write program area, then Flash memory area and configuration. Program will read the chip to get OSCCAL, then ask should it use calibration word from file. Verify it with documentation if you have any and click the lightning icon to write the file into chip. Now load the HEX dump, look for change of configuration bits on the right panel of IC-Prog window. In my case I found that this small PIC chip starts to terribly drain Vpp when turned on, so it was needed to increase Vpp to 15V and Vcc to 5.5V or it was not reading at all, giving entire read of 3FFF. If it is 3FFF, it means that chip haven't been read properly and it's needed to correct something.

Now the first thing is to read chip and check last 16-bit word in Program Code dump hex view. Select the proper chip from the combo box on the right. In a typical Willem PCB3 board pin 1 of ICSP header is located closer to Vcc selection jumpers. Alternatively you may use ICSP header, connecting its pins to the proper pins in PIC. Exactly opposite to method EPROMs are usually inserted to the main socket (where ends opposite to notch must match). Ignore hints potentially given by IC-Prog and insert it in 18-pin DIP socket for PIC programming, with pin 1 corresponding to pin 1 of socket (notches match). > Three jumpers (two near socket, one near switches block) as for reading ordinary EPROM (e.g. Now you are ready to configure Willem board to use ICSP:

Select parallel port you have connected programmer in and don't select any inversion checkboxes. WILLEPRO is a Willem programmer compatible up to PCB 3.0. First, click the plug icon and select "WILLEPRO" programmer, give it a nice delay (4-8) to coexist with programs running in background like Antivirus or drive emulators.

In Windows XP, you may need the driver called UserPort made by Thomas Franzon to make parallel port easily accessible from software which use direct hardware access. In Windows 9x it will run out of the box. The alternative software is called IC-Prog and can be downloaded in IC-Prog Website. It's really easy to erase OSCCAL with Willem software, especially 0.97 versions line. So to program a PIC, you have to read it first, get OSCCAL value and program a new dump with old value good for the particular chip you have in programmer. This word is used to calibrate internal RC oscillator and is set separately for each chip in factory, where RC characteristics are verified against real timing. First of all, PICs have not only configuration bits (like AVR's Fusebits), but also factory-configured last 16-bit word called OSCCAL word. It is not well prepared for programming PICs. The first rule when programming PICs in Willem is to avoid Willem software. But it is still possible to write to the chip. Of course Willem has no support for them. It contains even source code! I obtained a blank PIC chip and tried to program it in Willem programmer PCB v.

Following the "DIY" principle I downloaded an archive from Eurasia.nu with dumps of MultiMode 3 mod chip for PIC12F629.
